In the pictures, the couple can be seen walking down the street together looking angry AF at each other.
According to an insider, Sofia has been getting on her 34-year-old bae's nerves lately.
"Sofia is starting to annoy the s**t out of Scott," the source told Radar Online.
The pair's relationship is reportedly moving waaaay too fast for the father-of-three.
The insider adds: "Sofia is starting to tell people that Scott is her husband and suggested that they should move in together. He was not okay with that!"
Meanwhile, in a recent episode of Keeping Up With The Kardashians, Scott joked with ex bae Kourtney Kardashian that they should get married when they're 40.
An arrangement that we're sure wouldn't have gone down well with his model bae.
"Scott is starting to realise that he got into this for all the wrong reasons and he is not happy around her anymore," the insider concludes.
Uh oh... celeb couple breakup alert?
